Abstract
The utility model relates to a bag type filter. The utility model is characterized in that a bar-shaped filter bag is arranged above a water flowing hole of a bottom board of a filter cylinder. The flexible filter cloth of the filter bag is supported by a stainless steel bracket. The opening part of the filter bag is fixedly connected with the edge of the water flowing hole. The utility model has the advantage that the bag surface area of the filter bag is bigger than the area of section of the water flowing hole in multiple times, accordingly the filter area is increased, and the filtration efficiency is improved. The flexible filter cloth of the filter bag can shake under water flow impact pressure, and accordingly micro pores of the filter cloth are prevented from blocking. The cleanness of deposited impure granules is convenient, and the service life of the filter is prolonged. The bag type filter is suitable for separating and filtering impure granules in effluent purifying devices.
Description
The utility model belongs to the device of separate out suspended particle from liquid, the filter that particularly a kind of flexible filter bag that separates the impurity such as lignin in the paper waste is formed.
Paper waste process for purifying process, need will chemical reaction generates from waste water lignin separation come out.At present, adopt millipore filter usually.The structure of millipore filter is that densely covered small hole is set on filter, when relying on waste water by small hole, impurity particle is sticked to hole wall place, and separate with waste water.Millipore filter to pass through flow less, filter efficiency is lower, can not satisfy the needs of big flow fast reaction Processing Paper Wastewater.
The purpose of this utility model is, designs and produces a kind of filter bag type filter, and promptly installing strip filter bag on the water hole hole on the cartridge filter base plate to increase filter area, improves filter efficiency, adapts to the needs that the paper waste fast reaction is handled.
Filter bag type filter of the present utility model is made up of cylindrical shell, base plate, water hole, it is characterized in that, the strip filter bag is set above the water hole of base plate, and the flexible filter cloth of filter bag is supported by stainless steel stent, and filter pocket mouth is fixedlyed connected with the water hole edge.
Using method of the present utility model is, the filter bag type filter is installed in the flow process of paper waste, waste water enters from the filter cylinder bottom, enter the strip filter bag by water hole on the base plate, utilize the micropore on the filter cloth that impurity particle is trapped in the filter bag, clear water enters cartridge filter top by the micropore of filter cloth, finishes separating of impurity such as lignin and water.Utilize the flexibility of filter cloth, shake under water impact, the impurity that is trapped in the filter bag can be attached on the filter cloth, and can build up the below that is deposited in the cartridge filter base plate, by backwash, is then discharged by blow-off pipe.
The utility model has the advantages that the bag surface area of filter bag increases greatly than the filter bag cross-sectional area,, improved filter efficiency so can greatly increase filter area.The flexibility of filter bag is convenient to shake under water impact, is difficult for stopping up the micropore of filter cloth, is convenient to clean, and prolongs the service life of filter.Be applicable to that separate impurities is filtered in the effluent purifying device.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the organigram of filter bag type filter;
Fig. 2 is the A-A profile of Fig. 1.
By Fig. 1,2 as seen, the filter bag type filter is made up of the regularly arranged water hole of offering on cylindrical shell 1, base plate 2 and the base plate 3, is connected with strip filter bag 4 in the water hole upper fixed, and the flexible filter cloth of filter bag is supported by stainless steel stent 5.Cylindrical shell is provided with water inlet pipe 6, outlet pipe 7, and backwash tube 8 is established on the tube top, and blow-off pipe 9 is established at the tube end.
